I have not posted on this thread but have read it over a period of time and smiled several times to myself.

Thanks Mike for taking the time to show the correct stuation as we beleived it too be.

The confusion (much as your post shows) comes when after market tools show the wrong information and interprit things wrongly.

As I have said many times recently how can we trust programming of new modules with these tools. People here even seem to question if we need tools to program new units.

I think a big wake up call is going to happen soon and diagnostic work will return to the specialist who has invested in the right tools and has the knowledge to fix the cars.

I am now seeing so many cars that come to me with customer saying so and so's scanner said this and he fitted this and this and its a little better.

b#####cks its no better at all because he did not do any diagnostic work at all just fitted what his scanner said (if it pulled or interpreted code correctly) and then guessed at what to do.

I see the same with aircon machines. The salesman have been very busy and done well. Just about every repairer has a machine but often has not got a clue how air con works.

I think aircon and scanners have been sold because the garages out there are scared about whats happening for the future and they are being told they must have these to stay in business. Scare tactics.
